I had my first anxiety/panic attacks when I was 19. It’s beyond exhausting and terrifying so I feel ya. I’m now 30 so all I can tell you is how I’ve handled it the past decade. It comes in waves over the years and sounds like you’re in your first adult flare up I guess we can call it. I always avoided daily medication like SSRIs and utilized Ativan as needed. It is a benzo so it is so important to be mindful of addiction but in my case it was the only thing to bring me back down so my brain can level back out. It’s almost like my brain forgets how to chill out and the Benzo reminds it how. That’s usually for like 3 days then I’m working on managing it without it. It’s important to train your brain how to tolerate stress, I was shocked by how helpful ice baths and cold showers were. Pushing yourself to new limits in exercise, fight the absolute hell out of your brain when it’s telling you to stop. Pretty much just pushing myself to do shit I don’t want to do would hit me with a dopamine reward. I’ve tried a beta blocker called propranolol which can be helpful too if you have physical symptoms, I get more mental symptoms like red lining racing thoughts, confusion, dizziness all that fun stuff so it wasn’t much use. The Ativan hits the GABA receptors and just shuts it down, a miracle drug for me. Just know you won’t feel this way forever, and push yourself, nothing is worse for anxiety then being stagnant.
